Is there any truth to what I am hearing about the incompatability of the Polar HR monitors (I have an S150, but am thinking of getting the S625x) and the Cat Eye wireless speed/cadence computer? I found a good deal on the cat eye on ebay, but didn’t buy it becaues the guy said he is selling it becuase it interferes with his HR monitor? Anyone have experience with this. … I would like a cadence sensor (never have had one) but don’t want to deal with the wires. Help appreciated!!!
thanks

i got a cat eye wireless speed computer (no cadence) and i use a s625x. never had any interference.
I had some issues in the beginning, just switching the watch to the other wrist solved the problem. Eventually I found a better location for the display and now I don’t have any problems at all.
I love the Cat Eye, except for when I run my Hed Deep rear wheel I can’t use the cadence sensor
I have the cateye wireless with cadence and a Timex bodylink with HR and GPS. All 4 systems work fine without interference.
You are absolutely correct - the two products interfere with each other. Both work on the same radio frequency. When I use both products together, the Polar HR monitor “hears” the CatEye and will actually give a HR of 200-300.
I spoke with the polar rep recently and he reported that, although Polar was well aware of the problem, they were unwilling to modify their product to be compatible with CatEye. “We had the radiofrequency first” was what he told me.
As for the two products - after long consideration, I’ve finally decided to actually ditch my polar in favor of keeping the CatEye. I haven’t found many companies that make a quality wireless odometer and cadence sensor and the convenience and quality of the CatEye outweighs the benefits of a polar HR monitor - its a fantastic product. There are many companies which also make HR monitors which work in digital which I’ve been told wont cross talk with CatEye.
The Polar rep also told me that polar makes a combo product that has wireless HR and Cadence/odometer - however, it only works on the bike and you cant take it running. Not very practical for the triathlete…
How dissapointing that two quality companies with such great products cant get together and come to some sort of solution. I was truly disappointed by Polar’s reply that they simply weren’t willing to work with or accomidate CatEye because “we had the frequency first”.
Well, what of the guy above who had no problems after moving it slightly?
Also, does anyone else think this is a troll? 1st post ever by “JKD”
Have the exact problem. Have a Polar 120 and the Cat CD300. My watch does go completely haywire from both items. I do still use them both since I function better when I train on my bike via RPE rather than HR. But I then use the HRM for the run just to keep things honest
funny…I was just getting ready to post one in the classified section here–for that very reason.
I bought one for my wife, who loved the computer, but her Polar wouldn’t work with it. She ended up getting a P-tap–moving the receiver didn’t really help.
not sure what a “troll” is. Just trying to be helpful. yup, my first post, and jkd - simply my initials. sorry for the confusion…
I believe I read somewhere that Cateye corrected the issue after the first few months. Can’t recall the source though.
CD300DW and Polar 720i, mounted on the bars next each other or wearing the 720i on my wrist… either way, no problems.
I have the cateye wireless with cadence and a Timex bodylink with HR and GPS. All 4 systems work fine without interference.
“4 systems”… are you in an F-18 or riding a bike 
I once rode with a guy who had a watch, a bike computer, a heart rate moniter and two gps units on his bike.

Some people forget that you get faster by “riding” not “reading”
I also have no problems with the Cateye double wireless and the new Polar RS200SD.
I do often feel a bit “dumb” looking at my speed, cadence and HR all at once. Now about that power monitor …
why not just use a 625x or 720i, which has bike functions…
I have a polar s210 with “own code” . If I start the hrm first before riding with the cd300 then I have no problems. If start riding before starting the hrm then the cateye interferes with the hrm.
